ABSTRACT:
Continuous concentration of solar heat on a fluid contained in a fixed, spherical boiler chamber, whereby the fluid is vaporized and thus drives a turbine, is effected by means of a paraboloidal reflector to which solar countermotion about the boiler center point is externally imparted by a carriage. Mounted on a base of variable configuration, the upper surface of which lies in a polar plane, a single configuration of reflector and carriage will operate throughout the time from sunrise to sunset on every day of the year, without structural change, at any suitable site in the torrid and temperate zones of the earth, regardless of the lattitude of the site. The turbine and boiler chamber are supported by cantilever members of an independent power plant structure. Reflector efficiency is maximized by the absence of shadow, brought about by the omission of that part of a conventional, fully circular paraboloid which would traverse the shadows of said turbine and of said cantilever members. Heat loss is minimized, thereby maximizing thermal efficiency, by location of the turbine above and in close proximity to the boiler chamber, said location being facilitated without shadow by the reflector shape and orientation.
